To all whom Iit 'may concern: 'Be it known that I, AReHiBALn HYDEy ILILE, a citizen of the United States, residing in. Ihiladelphia, Pennsylvania, have invented certain improvements in Controlling4 Mechanism for Clutches, of which the following is a speciiication.

The object oi" my invention is to provide a simple and ell'ective means 'for controlling clutches ior throwing into and out oiI the mechanism between. a drivinl and a driven shaft;

.section on the linc'Z-A'm, case removed; Fig. 3, is a section on the hue slide on, but must turn with the shaft. v thepresent instance, the clutches are shown disks beine' mount id hote.

O the trucks and a controller no untcd on the 'Y car body.

Figure i, is plan view oi a portion oi a car truck illustrating in i'liagri'im my improved ccntrolling mechanism; Fig. 2, is a l, with the gear 3 3, Fig. 2, illustrating one of the clutches in section, and Fig. 4, is a vertical section ol one of the magnetic valves used in connec tion with. my invention.

Referring tothe drawings, Il is the frame of a car truck in the present instance of the 'pivoted or swing type, having boxes for the axle I on which the ilanged wheelsi i are mounted.

C, C, are tivo driving shafts `vwhich in the present instance are the crank shaft of tivo gas'olene engines, these shafts are mounted in, suitable boxes cand each sha'l t has a 'pinion c at one end.

A is an intermediate shaft mounted in suitable bearings on the frame H and on this shaft A are two sets of bevel wheels B, B', each set includes two bevel wheels I) b', loose on the shalt, and an intermediate clutch sleeve B2 keyed to the shalt so that it can l In as plate fric tion clutches (Fig. 2l), two sets of n each wheel and the clutch s Jvc, but it will be understood that any i" i oi. clutch may lic used without departing lrcro my invention.

When a clutch sleeve B is ino ved in. one direction, one bevel gear clutched to the shaft A,and v:i en the sl ve is thrown in the 'opposite direc.. i. the ther bevel gear is ciutched to the shaft and the motion ol `the are loose upon the shalt and the sleeve'is4 spiincd to the shaft, so that it can slide on but inust turn with the shalt.

'The two gear wheels D D rncsh respectively with gear wheels F ll", ot dilliercut di` aineters, on the driven shaft or axle I. 'lhus it will be seen that the power is transmitted from the driving shafts (l C" through the gearing on the intermediate shalt A to the axle or driven shalt l, and the clutch n1echaiiisin so arranged that either one or both ol` the driving slia'lts can be `geared to thc vdriven shalt, or the direction of movement of the driven shalt can be reversed.

J J are rock shafts having forks 7" engaging the sleeves B2 B2, and thc shalt J has an 80 arm engaging a plunger rod m. The plungors of this rod arc adapted to air cylinders M M The shalt J" has an arm y" engaging a rod ni having plungers adapted to air cylinders M'M. lVhen air is admitted into the cylinders M and M2 thc clutch sleeves are moved in one direction, and when air is admitted into the cylinders M and M3 the clutch sleeves are moved in the opposite di! rection. v

The central rock shaft J2 has a fork .9'4 engaging the sleeve D2 and an arni engaging a plunger rod m2 having plungcrs Working in the cylinders MA and M5.

Each cylinder is provided with a magnetic valve E ol the solenoid type constructed as illustrated in Figs/i; these valves control the ilow of air to and from the several cylinders. In the p Iosent instance the air cylinders M M M2 Mi are mounted on one side ol a plate Il rigidly secured to the l'raine oll the truck, and the air cylinders M" and M are mounted on the opposite sido of said plate, making a very rigid and substantial construction. 'i

The passage from cach valve connects with; the rear of its cylinder and the inlet portis connected to a pipe e; the pipes e extending from each valve are coupled to a manifold direction or forward A, l/Vhen the switch n is vand cut-outs n and n3. lThe switch n concentral, and consequently .both clutch sleeves pressed air is stored.

N is aV controller, in the present instance illustrated as a plat-ehaving switchesn n trols the engine clutches, the switch n conn trols the fast and sloW speed gear, and the` cut-outs are'for the purpose of cutting ont either of the two power shafts.

Wires llead from the several magnetic valves to the switchboard n, as clearlyY shown in Fig. l of the drawings. 'llicse wires can be carried through a cable o1' may be run in any` suitablezmanner, wheirthe niechanisni,

to be controlled moves ind'e'pemlentl \r of the part upon which the controller is mounted. If for instance,- 'asgsliown `in the drawing, the parts are mounted on the truch of a car the controller would be mounted on the car body and wires would lead from the ear body to the truck in a maimeiuthatwould provide for the free pivoting of the truck. Such a type of truck is illustrated iii the application for patent tiled byline on thctwen tv-second of July, 1.005, Serial Number 270,857.

Vhen the two cnt-out switches n2 ngare in the position the reverse to that. shown in F ig. 1 both clutch sleeves B2 can be controlled by the one switch n; when the switch n. is in the mid position both the rock shafts J J are are out of gear. l/Vhen the switch isithrown to the right contact is inade so that air will be admitted to the cylinders M M, and the 'driving shaft' will move theshal't A in one moved to the left ai; is 'admitted to the c.\f'l inders M M2 and the u'iovement of the shaft A is reversed. Vlfen theswiteli n is moved to the right thon the lever J2 is shifted so that i the high speed is thrown into gear, and when moved to the lett the low speed is `thi-own int-o gear. 'llnis the entire driving mechan- -isin is 'under the control of the oiwrator.

I claim as my invention se 1. The cinbinatioi-i of a shaft, a clutch sleeve thereon, means for shifting the said sleeve, air cylinders controlling the shifting mechanism, magnetic valve ineehanismforv controlling the admission of air to the said cylinders, and it controller having a switch lever thereon controlling the magnetic valves, substantially asdescribed.

2. ,The coinbination'of a shaft, two clutch v rock shafts, airAcylinders,"phingers in said cylinders, rods connecting the plnngei's ol' cach pair of cylinders and connected to an arm ot thc rock shalt, m'z'tgnetic valves' controlling the admission olV air to the said cylmders, a switch lever toi` controllingthe inagnetic valves, and cut-outs, forl throwing either one lor both of the clutch sleeves, under the control ol' t he switch, substantiall)7 as descrilmd.

4..' l`he mimbination of a shaft, elutcli` sleeves mounted on said shaft, rock shafts vfor the clutch sleeves, arms on each roch shaft, a pair of air c if'lin'ders, each pair havingr a plunger rod and each rod being connected to an arm ofa' rock shaft controlling a clutch sleeve, a magnetic air valve' for each clvlin- .dcr,'av controller, two cut-ents, and wires lleading from thev coi'itroller to the magneticvalves, the cut-outs being so arranged that either ,one or both of the clutch sleeves bctwcen thc driving shafts and theintermediate,

clu tch shaft can be operated, substantially asl dcscribw ln testimony whereof, l. have siffned iiiy\ nami` to thisl spwilication, inthe presence of two subscribing wit ncsses.
